I agree that it could not be used routinely for all fractures but I can think of a few situations where it could be revolutionary . Very complex fractures certainly, but even better for revisions. Think of fractures around a prosthesis, such as hip fractures. Because the surgeons have to remove bone in order to fit the prosthesis, if the bone is fractured later they are left with significantly less to work with and this currently leads to long, complex operations. By giving surgeons the ability to "remodel" they can increase the amount of bone they have to work with, hopefully improving outcomes. This certainly seems to offer a viable alternative. It could even be used in elective operations such as knee replacement revisions without the current loss of leg length.
Yes, that would be one of the few useful applications for this. The article that was linked however is ridiculously misleading, suggesting it could be used for broken noses and routine broken bones.
